Abstract

This research was to know the effect addition of coloring agent in the rations on the performance, the percentage of bursa fabricius, carcass and broiler chicken viscera's weight including liver, heart, kidney, gizzard and weight spleen broiler chicken. This research used 100 DOC Hubbard Strain, which was kept in litter system for four weeks. The ration was composed of 21% protein and 2900 Kcal/kg metabolism energy. Design used in the experiment was completely randomized design with four treatments, that were R1: ration with no coloring agent (control), R2: ration with the addition of 0.6% curcuma, R3: ration with the addition of 0.04% tartrazine, and R4: ration with the addition of 0.04% egg yellow. Each treatment used three replications and every replications used eight-broiler chicken. The variable observed was feed consumption, body weight gain, feed conversion, final body weight, percentage of bursa fabricius, carcass and broiler chicken viscera. The data were analyzed using ANOVA. If there was a significant effect, then it would be analyzed by Duncan's Multiple Range Test. The averages of feed consumption were: R1 (1111.44g), R2 (1021.61g), R3 (909.43g) and R4 (1078.75g). The body weight gains were : R1 (700.91g), R2 (652.36g), R3 (588.97g) and R4 (720.02g). Feed conversion were : R1 (1.59), R2 (1.56), R3 (1.51) and R4 (1.52). Final body weight were : R1 (742.70), R2 (695.56), R3 (629.37) and R4 (761.56). The result showed that all of the treatments did not give the significant influence to the feed consumption, body weight gain, feed conversion and final body weight. So that it can be concluded that the addition of coloring agent in broiler diet did not influence broiler performance. The result showed that using the feed coloring agent in the diets was highly significantly (P<0.01) decreased the percentage of bursa fabricius, which the averages of R1, R2, R3 and R4 is 0.21, 0.13, 0.09 and 0.11%. But there were not significant influence the percentage carcass and broiler chicken viscera. The averages weight of carcass were 58.74-60.02%, the weight of liver were: 2.7-2.92%, the heart weights were: 0.56-0.71%, the kidney weights were: 0.27-0.28%, gizzard weights were: 2.98-3.19% and weight of spleen were 0.21-0.23%. The conclusion was that the treatment did not give the significant effeel to the performance, percentage weight of carcass, liver, kidney, heart, gizzard and spleen. The result showed that using feed coloring agent in the diets was highly significantly (P<0.01) decreased the percentage of bursa fabricius. Keywords: performance, diet, bursa of fabricius, carcass, viscera.
